We may need to add a 'switch' DEVICE_TYPE in include/target.mk
selecting packages relevant for this class of devices.
('bridge' or 'ip-full', 'ethtool', ...)

It's rather the very limited performance of the CPU and Ethernet MAC
used for the CPU port which makes me disregard those (layer-2)
switches being used for anything else than that.

Exactly. I fully agree, none of those packages make much sense on this
class of devices and all of them should be dropped from default
installations. Obviously users may still install them if they really
want their switch to act as DHCP server and/or caching DNS resolver.
